Abstract

1455478 Stabilized copolyetheresters E I DU PONT DE NEMOURS & CO 30 April 1974 [30 April 1973] 18937/74 Heading C3R A stabilized copolyetherester composition comprises (a) a copolyetherester in admixture with (b) a diaryl amine antioxidant and (c) a nickel salt of a Schiff's base derived from salicylaldehyde and an aromatic amine, the copolyetherester being derived from (i) a poly(alkylene oxide) glycol of molecular weight 400-6000 and a carbon to oxygen ratio of from 2À0 : 1 to 4À3 : 1, (ii) a dicarboxylic acid of molecular weight less than 300 and (iii) a diol of molecular weight less than 250, and containing from 15-95% by weight of units derived from (ii) and (iii). The composition preferably contains from 0À2 to 5À0 weight per cent of the diaryl amine and from 0À1 to 3À0 weight per cent of the nickel salt, the percentages based on the copolyetherester. The composition may also contain carbon black, silica gel, alumina, clay or glass fibres. The examples describe compositions comprising (1) a copolyetherester derived from polytetramethylene ether glycol (molecular weight about 975), 1,4-butanediol and dimethyl terephthalate, optionally with dimethyl phthalate, (2) the following diaryl amine antioxidants: 4,4<SP>1</SP> - bis(α,2 - dimethylbenzyl)diphenylamine, phenyl - α - naphthylamine, phenyl - # - naphthylamine, dioctyl diphenylamine, N,N<SP>1</SP>- diphenyl - p - phenylene diamine and symdi - # - naphthylphenylene diamine, and (3) the nickel salt of the Schiff's base derived from salicylaldehyde and 2-chloroaniline.
